Why a forced c=* line in MESSAGE stream type ?

[Eric Dev]

RTPEngine always add a c=* (connection information) line for MESSAGE stream type with ip address from original sdp.

what's the reason for that choice/behaviour ?

shouldn't be this transparent ? if no c=* line in original MESSAGE stream type just keep it as it is ?

[Richard Fuchs]

`m=message` is understood to be MSRP, which normally uses TCP transport.
We don't support TCP at the moment, so an MSRP media section without c=
line that falls back to the session-level connection address would
break. And so just adding a media-level c= line with the original
address gives you a better chance of a working connection.
